Second set of new devices, functionality and cleanup for IIO in the 4.1 cycle.

New Functionality
* Watermark logic for buffers.  Allows for blocking reads to block until
  their requested amount is available - previously they only blocked until
  a single scan of data was available.  Also allows for polling for a
  watermark amount of data to be available.  This feature was first proposed
  some time ago to good responses, but not taken further by the original author
  Octavian has picked up the gauntlet and taken it through
  to merging (along with the hardware fifo support that follows).
* New approach to hardware fifo handling - in particular handling the
  interaction of a hardware fifo feeding into a software fifo and their
  watershed events.  We don't have every possible case well covered yet,
  but this is certainly a good, flexible starting point.  This will replace
  the previous approach used in ancient drivers (sca3000) where we just
  exposed the hardware buffer directly to userspace.  Very few pieces of
  hardware have sufficiently long buffers for that to be an adequate solution.
* bmc150_accel - hardware fifo support.
* mlx90614 - support dual IR sensor devices + some refactoring to clean up the
  code and allow some other functionality currently under review.
* L3GD20H gyroscope support added to the st_gyro driver.
* lis3lv02d accelerometer added to the st_gyro driver. Note this part is
  also supported by the older lis3 driver under misc.  A lengthy discussion
  took place and concluded that holding parts out on the basis that whole
  driver would be subsumed into this one was counter productive.  Better
  to add part support and add additional features as people need them.
  Basically there was not advantage in not merging the support.
* max517 driver gains support for MAX520 and MAX521 DACs.

Documentation
* 3.20 -> 4.0 renaming for recent docs. Whilst technically a fix, I think
  people will cope until the next merge merge window.
* An ABI typo hat -> What:  More ABIs should have hats.
* Document in_rot_offset, illuminance_raw and illuminance_scale.

Cleanups
* Fix a scale extraction bug in generic_buffer.c example.
* Constify a load of device tree related structures.

IIO fixes for 4.0 set 4

A couple more IIO fixes.

* Fix check for HAS_IOMEM in the cc100001_adc driver to avoid build errors.
  Rather curiously it was ORed with Regulator and clock support.
* vf610 driver was trying to use an ADC clock outside the possible
  spec on some boards.  The driver assumed a fixed clock speed previously
  across all boards, but that is not true.  This fix ensures that the
  reported frequency is correct on all boards.
* The adis imu common code directly set the current trigger to the
  driver supplied one.  Unfortunately this didn't increase the use count
  leading to a double free via a particular path of changing the trigger
  then removing the driver.

Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
 * VHT support for TDLS and IBSS (conditional on drivers though)
 * first TX performance improvements (the biggest will come later)
 * many suspend/resume (race) fixes
 * name_assign_type support from Tom Gundersen

Late GPIO fixes:
- Syscon GPIO fix for Keystone DSP GPIOs
- Pin number translation fix for ACPI GPIO
- A smallish compiler warning fix on the mpc8xxx driver

Linux 4.0-rc6

- DP link rate refactoring from Ville
- byt/bsw rps tuning from Chris
- kerneldoc for the shrinker code
- more dynamic ppgtt pte work (Michel, Ben, ...)
- vlv dpll code refactoring to prep fro bxt (Imre)
- refactoring the sprite colorkey code (Ville)
- rotated ggtt view support from Tvrtko
- roll out struct drm_atomic_state to prep for atomic update (Ander)

sound fixes for 4.0-rc6

Three trivial oneliner fixes for HD-audio.  Two are device-specific
quirks while one is a generic fix for recent Realtek codecs.

This is the 3.14.37 stable release

This is the 3.10.73 stable release

This is the 3.19.3 stable release

Allwinner defconfig changes for 4.1

Nothing really standing out here, just a few options to enable in the defconfigs

Allwinner fixes for 4.0

There's a few fixes to merge for 4.0, one to add a select in the machine
Kconfig option to fix a potential build failure, and two fixing cpufreq related
issues.

Allwinner clocks changes for 4.1

The usual round of clock changes for the Allwinner SoCs.

There is nothing really standing out here, but a few changes and fixes, most
notably to allow the AHB clock to be parented to a PLL, instead of the CPU
clock to avoid any AHB rate change due to cpufreq.

regulator: Fixes for v4.0

Two fixes here, one typo fix in the documentation and one fix for a
system hang with one of the Palmas chips caused by the use of an
incorrect offset being provided for one of the registers.

iwlwifi:

* avoid panic with lots of IBSS stations
* Fix dvm's behavior after suspend resume
* Allow to keep connection after CSA failure
* Remove a noisy by harmless WARN_ON
* New device IDs

rtlwifi:

* fix IOMMU mapping leak in AP mode

brcmfmac:

* disable MBSS feature for BCM43362 to get AP mode working again

ath9k:

* disable Transmit Power Control (TPC) again due to regressions

* fix beaconing issue with AP+STA setup

Linux 3.18.10
